cavity back iron

    These clubs get their name from the hollowed-out space on the back of the clubhead. This cavity is formed when most of the club’s weight is distributed around the perimeter. (The term “cavity-back” is synonymous with “perimeter-weighted.”)

    Cavity-back irons feature a larger effective hitting area and sweet spot than traditional, blade-style irons, and produce longer, straighter results on poorly struck shots. This makes cavity backs a popular choice among mid- to high-handicap golfers. Perimeter weighting also creates a “gear effect” which causes off-center hits to curve back toward the target.

    Many, but not all, cavity-back irons have larger heads than blades. Thomas Golf ( offers a variety of cavity-back iron sets.
